Abstract
The invention discloses a kind of casting processing method of fusible pattern, pump housing casting method provided by the invention, including resin sand is used as raw material, and sand mold is made using resin sand, with forming resin bonded sand mould after mould mould assembling, then the making of potting syrup is carried out, the degree of its material chemical component is as follows：C：3.0‑3.2%；Si：1.8‑2.0%；Mn：0.4‑0.5%；P：0.08%；S：0.01%；Mg：0.03‑0.04%；Re：0.01‑0.02%；Cu：0.6 0.8% or Sn：0.04‑0.05%；Remaining is Fe；Above-mentioned raw materials are heated to smelting temperature in electric furnace, make alloy fully melt to form molten iron, form potting syrup；Described potting syrup is poured into a mould into resin bonded sand mould, casting is formed after solidification；After casting all cooling, through sand removal, then it is heat-treated.Technical scheme improves production efficiency, reduces production cost, and casting quality has been effectively ensured.
Description
Technical field
The invention belongs to pour into a mould manufacture field, the casting processing method of specially a kind of fusible pattern.
Background technology
In the prior art, full form casting process, it is exactly briefly that meltability model is made with fusible material, thereon
If the special fireproof coating of coating dried layer, after drying and hardening forms an overall shell, then with steam or hot water from type
Melt model in shell, then shell is placed in sandbox, fill dry moulding in its surrounding, finally casting mold is put into roaster
By high-temperature roasting, casting mold or shell it is fired after, obtain casting in wherein casting molten metal.But casting dimension can not
The too big slow model castings of complex technical process casting cooling velocity are in all blank forming methods, and technique is most complicated, casting
Cost is also very high, but as fruit product select it is proper, Element Design is reasonable, high casting cost due to reduce machining,
Assemble and save metal material etc. and be compensated, then model casting there could be good economy.
The content of the invention
In order to overcome above-mentioned technical problem existing for prior art, the purpose of the present invention overcomes lacking for prior art
Fall into, there is provided one kind can enhance product performance, and the casting processing method of the fusible pattern with good economy.
A kind of casting processing method of fusible pattern, it is characterised in that：The casting processing method comprises the following steps：
(1) wax-pattern is made；By in the material injecting mould of the making wax-pattern of various blending constituents, condensation is molded；It is described various mixed
The raw material of the making wax-pattern of synthesis point is formulated by weight, including：Paraffin：40-50；Octyl stearate：20-25；Microwax：
20-30；Tissuemat E：15-20；Dimethylbenzene：3；
(2) shell is manufactured；In the coating of wax pattern surface uniform fold one, then stucco is reinforced, and is dried, is obtained shell after hardening；
The coating includes：Waterglass, silica flour, silica sand, deionized water, surfactant and defoamer；
(3) shell is subjected to steam dewaxing, roasting；Shell with wax-pattern is placed in 75~85 DEG C of hot water,
Wax material is set to be flowed out after melting from running gate system；
(4) shell is calcined；The shell after dewaxing is put into heating furnace again, is heated to 850~900 DEG C, insulation
1~2 hour, residual wax and moisture in burning-off shell；
(5) aluminium alloy is poured into a mould into the shell after roasting, after solidification manually or investment casting method removes shell, will be obtained
Casting be processed by shot blasting, formed casting.
A kind of casting processing method of fusible pattern of the present invention is a kind of method of high economic benefit, strictly to each stage process
Parameter is controlled, and improves properties of product, and process substantially reduces, and technique is simple.
Embodiment

The raw material of the making wax-pattern of synthesis point is formulated by weight, including：Paraffin：40-50；Octyl stearate：20-25；Microwax：
20-30；Tissuemat E：15-20；Dimethylbenzene：3；
(2) shell is manufactured；In the coating of wax pattern surface uniform fold one, then stucco is reinforced, and is dried, is obtained shell after hardening；
The coating includes：Waterglass, silica flour, silica sand, deionized water, surfactant and defoamer；
(3) shell is subjected to steam dewaxing, roasting；Shell with wax-pattern is placed in 75~85 DEG C of hot water,
Wax material is set to be flowed out after melting from running gate system；
(4) shell is calcined；The shell after dewaxing is put into heating furnace again, is heated to 850~900 DEG C, insulation
1~2 hour, residual wax and moisture in burning-off shell；
(5) aluminium alloy is poured into a mould into the shell after roasting, after solidification manually or investment casting method removes shell, by what is obtained
Casting is processed by shot blasting, forms casting.
It is described above, only it is embodiments of the invention, not the present invention is imposed any restrictions, it is every according to the technology of the present invention
Any simple modification, change and the change of equivalent method that essence is made to above example, still fall within the technology of the present invention
In the protection domain of scheme.
